Application led April 7, 1921. Serial N o. 459,498.

To all whom t may concern Be it known that 1, IRA AN'rHnr Kanus, a citizen of the United States, and a resident of Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful lmprovements in Sand-Settlers, of which the following is a specification.

This invention relates to a sand settler or trap for deep well pumps.

The object of the present invention is to provide a settler which may be easily attached to the working barrel of a deep well pump, and adapted to cause any sand which may be carried into the settler with the oil, water or other liquid being pumped from the well, to be entirely settled or precipitated from the oil or water before the same passes into the working barrel of the pump.

Other objects and objects relating to details of construction, combination and arrangement of `parts will be hereinafter pointed out in the detailed description to follow.

The invention is illustrated by way of eX- ample in the accompanying drawings, in which:

Figure 1 is a central longitudinal section of the upper end portion of the settler,

Fig. 2 is a similar view of the lower end portion of the settler,

Fig. 3 is a cross section taken substantially on the line 3--3 of Fig. 1,

Fig. 4 is a cross section taken substantially on the line 4 4 of Fig. 2.

Referring to the drawings more particularly 10 indicates the head of the settler which consists of a short tubular section with l relatively thick walls and a relatively small bore 11, as shown. The upper end of the head is reduced and threaded as at 12, and at an intermediate point of the bore 11 there is formed a wall 13 which is provided with a central threaded opening adapted to receive the threaded end of a tube 14. Below the wall 13 the bore is enlarged as at 15 and said enlargement is provided with threads as at 16 adapted to receive the threaded end of the pipe 17. The enlargement 15 terminates in a second enlargement 18 which is likewise threaded as shown, and adapted to receive the threaded end of the pipe 19. Also the lower end of the head 10 is reduced and threaded as at 20 and adapted to receive the interiorly threaded end of the pipe or casing 21.

. well.

The tubular member 14 terminates at its y lower end above the lower end of the pipe 17. The lower end of the tubular member 14 is closed by the means of a plug as indicated at 22 and above this plug a portion of the member is perforated as indicated at 28. The lower end of the pipe 17 is connected to a similar pipe section 24 by the means of a sleeve 25. Also the lower end of the pipe section 24 may be interiorly threaded for connecting to other pipe sections, not shown. The lower end ofthe pipe 19 terminates at a point considerably above the lower end of 'the outside casing 21, as shown in Fig. 2.

The pipe 19 is opened at its lower end as 4likewise shown, and from this point lcommunicates with the interior of the casing 21; and also communicates with the pipe 17 through the perforated portion 26 of said pipe, said perforated portion being at the upper end of the pipe, as shown in F ig. 1. The lower end of the casing 21 is likewise threaded as at 27 and adapted to receive the one end of a nipple 28, the nipple being preferably reduced as at 29 and threaded at its lower end as at 30, to which a section of pipe may be connected if desired. The casing 21 also has an upper end portion which is perforated as at 31,' Fig. 1.

1n the operation of the present device, the'head 10 is suitably connected to the working barrel of the pump by means of a sleeve into which the threaded end 12 may be screwed. The casing 21 will then of coursel be immersed in oil or water depending upon what is being drawn from the The oil or water will pass throu h the perforations in the portions 31 of t e casing 21 and from thence pass downwardlyy as indicated by the arrows until the lower end of the pipe 19 is reached, at which time the oil or water must then pass upwardly and into the pipe 19. At this period any sand carried by the oil or water will to a great degree be precipitated or settled, and collected between the casing 21 and the pipe 17, as shown in Fig. 2. The oil or water then continuing will pass from the pipe 19 through the perforations in the upper end portion of the pipe 17 and from thence downwardly through said pipe 17 until it reaches the perforated portion 23 of the tubular member 14, at which time it will pass into the tubular member 14 and from thence be carried through the head member 10 and into the working barrel of the pump. At the time oli' its passage from the pipe 17 into the tubular member 14 any sand or other foreign matter carried by the oil or water will again have a chance to settle out and separate therefrom and drop in between the tubular member and fall into the lower end of the pipe 17, as shown in Fig. 2.

If desired, an extension may be made to both the casing 21 and the pipe 17 in order to provide a larger receptacle for the settling sand. It may be here pointed out that during the passage of the oil or water through the settler it is subjected to twoV intervals for separating therefrom, the sand or other foreign matter which the same may carry, one interval being at the time when the liquid passes from the casing 21 upwardly and into the pipe 19, and the other interval being at the time when said oil or water'passes from the interior of the pipe 17 through the perforations in the lower end of the tubular member 14. It alsomay be here pointed out that the tubular members are in graduated spaced relation with one another, the two outermost casings being the greatest distance apart and the two innermost the least distance apart, as shown in the drawing. Y This ar- Y from the oil ,and water.

k1While I have shown and described the preferred form of my invention, l wish it to be understood that I am aware of the' vof telescoping tubes extending from the other end of said head, said tubes being in graduated spaced relation, the greatest space occurring between the outermost tubes, and the innermost tube communicating with the interior of the tubular hood inember while the outermost tube has a portion thereof perforated and all the tubes communicating with each other and with the innermost tube at alternate ends.

2. A connecting head for a sand settler of the character described comprising a cylindrical member having a central longitudinal bore and a reduced upper end portion which is threaded and adapted to be connected to the worlrigng barrel of a pump, a partition wall in said bere having a threaded central passage, adapted for receiving the exterierly threaded end oi' the innermost tube of the sand settler, andsaid 'bore having a threaded lowerend portion of the character described, comprising av cylindrical member having a central longitudinal bore and a reduced upper end por- 'tion' which is threaded and adapted to be connected to the working barrel of'a pump, a partition wall in said bore having a threaded central passage adapted for receiving the exteriorly threaded end of the innermost tube ci the sand settler, said bore having a threaded portion adjacent its lower end, and also an enlargedV portion likewise threaded which are adapted for receiving the exteriorly threaded ends of intermediate tubes of the sand settler, a reduced threaded portion formed upon the exterior and lower end oi the connecting head, adapted for receiving an internally sand settler.
